Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a timepiece mechanism for, for example, a portable alarm clock.

(Prior art) The clock mechanical body of an alarm clock in the prior art generally has two or three upper and lower panels arranged oppositely.
A clock train was built into the main plate, and a dial was provided at a predetermined distance from the upper plate.

(Problem that the invention attempts to solve) The conventional watch mechanical body is made of two or three pieces like this.
Because two main plates were used and a dial was required, the mechanical body of the watch inevitably became thicker than a certain level, which placed a limit on how thin the watch could be.

SUMMARY OF THE INVENTION An object of the present invention is to provide a thinner alarm clock mechanical body for making the clock thinner.

(Means for Solving the Problems) Therefore, the feature of the present invention is that it consists of a plurality of shaft supports, a clock train, a dial, a support, an alarm setting ring, an outer case, and an alarm display body. The pillar is integrally provided on one side of the main plate and is integrally protruded with the main plate, and its tip surface is on the same level, the clock train is rotatably supported by the shaft support, and the dial plate is rotatably supported by the shaft support. The above-mentioned alarm setting ring is provided in such a way that it touches or can come into contact with the tip surface of the column, the column is formed on the main plate, and the tip surface touches the dial, and the alarm setting ring is attached to the edge of the opening of the outer case. It is rotatably mounted on the front side of the alarm, and in cooperation with the pillar supports the dial, and the alarm display body rotates together with the alarm setting ring.

(Example) An example of the present invention will be described below with reference to the drawings.

As shown in the figure, the lower case 1, which is the base plate, is made of a resin molded product. A plurality of shaft supports 1a, 1b, and 1c are integrally formed on one surface of the lower case, and the upper end surface of all of them is They are aligned at the same height (level). A clock wheel train 2 consisting of a rotor pinion 21, a second wheel & pinion 22, a third wheel & pinion 23, etc. is incorporated in each of the shaft supports 1a. Axial support 1a...
The tip portion of the gear train 2 is slightly protruded from the upper end surface of each of the gears 21 to 23 of the train gear 2. In addition, the lower case 1 includes a support 1d having the same height as the shaft support 1a.
... is protruding, and this support and the shaft support 1a...
A dial 3 made of an aluminum plate is in contact with the upper end surface of the dial. An alarm setting ring 4 is slidably abutted on the outer periphery of the upper surface of the dial 3, and the dial is held between this ring and the end surface of the support column 1d. Therefore, the wheel train 2 is rotatable between the lower case 1 and the dial 3. Of course, the dial plate 3 may be in contact with the end surfaces of the shaft supports 1a, or may be slightly separated from the end surfaces of the shaft supports 1a, as long as they can come into contact with them.

A transparent alarm display board 5 is placed on the inner step of the alarm setting ring 4, and the center of this alarm display board 5 is connected to an alarm setting shaft 7 provided around the pointer shaft 6. ing. Outer case 8
A locking protrusion 8b is formed at the upper end of the inner circumference of the dial window, which is an example of an opening, and by locking the protrusion 4a formed on the outer circumference of the ring 4, the ring 4 can be Dislodgement is prevented. and,
A glass edge holder 9 fixes the alarm display plate 5 by engaging with the ring 4, and a front glass 10 is fixed to this glass edge holder. Therefore,
By rotating the glass edge presser 9, the alarm display plate 5 can be rotated in conjunction with the ring 4.

An outer case 8 is fixed to the upper surface of the lower case 1 with screws, and a large number of click grooves 8a are formed at equal intervals on the inner circumference of the outer case. A projection of a spring (not shown) comes into elastic contact with this unevenness, thereby producing a click action.

To assemble the present invention, the watch wheel train 3 is assembled together with the watch parts into the lower case 1, and the dial plate 3 is brought into contact with the tip surfaces of the shaft supports 1a, .
Then, the alarm setting ring 4 may be engaged with the outer case 8, and the alarm display plate 5 and the glass edge presser 9 may be engaged with the ring 4. In addition, clock train 2
is located between the lower case 1 and the dial 3, and even if pressing force is applied to the dial 3 from above and below the watch, the dial 3 is supported by the tip surface of the shaft support 1a...
to prevent deformation of the lower case 1 and dial 3.
The distance between the clock wheel train 2 and the dial 3 is ensured.
Since they do not come into contact with each other, the clock train wheel 2 is not compressed and the rotation of the train wheel is not hindered.

(Effects of the invention) As described above, according to the invention, one side of the conventional main plate is omitted, which is effective in making the watch thinner. All you have to do is assemble the clock train, place the dial facing each other, engage the alarm setting ring on the outer case, and bring this ring into contact with the dial, which speeds up the installation of the watch train, and also allows the dial to be attached to the dial. Even if a pressing force is applied, it is supported by the tip of the shaft support, which prevents deformation of the dial and does not interfere with the rotation of the watch wheel train. It is held firmly and the alarm setting is easy.
